On Wednesday, Google published a scientific paper in the journal Nature detailing how its quantum computer vastly outpaced a conventional machine, an idea called quantum supremacy. Powered by a Google-designed quantum processor called Sycamore, it completed a task in 200 seconds that, by Google's estimate, would take 10,000 years on the world's fastest supercomputer. Google's success at achieving quantum supremacy sounds like a momentous victory. But really, it's just the first step in making this radical new type of computing useful.
On Wednesday, Google published a scientific paper in the journal Nature detailing how its quantum computer vastly outpaced a conventional machine, an idea called quantum supremacy.

Quantum computers work by embracing the strange nature of particles at the atomic scale. Where classical computers store data as bits that are either a one or a zero, the quantum computing equivalent, called a qubit, can store information that's part one and part zero. Next, a quantum computer gangs multiple qubits together, dramatically increasing the number of possible states they can record. Last, processing those qubits lets researchers explore countless possible solutions to a problem simultaneously instead of evaluating them one at a time. It's lousy for adding two and two, but potentially great for some problems classical computers just can't cope with.
